    Followed the instructions but now the phone will not boot.
    After the Sony Logo, the notification led goes green and the battery charging icon appears on the scren just to dissapear a couple of seconds later.
    This happens even if the phone is not connected to the cahrger.

    Did I just kill the phone?

      No, You certainly haven’t killed it. Just try to upgrade it again and it will work fine.

        Tried it a couple more times and got the same result. It will say all went OK but after reboot the phone will not even turn on (behaviour described above)The log will show missing files error (external_sd and emmc).
        I finally reverted back to the Sony Firmware via Flashtool and the phone is now working fine.
        One thing I noticed is that both files, for the xperia miro and the xperia tipo are the same (XPETIPOICS_) Shouldn’t the files be different as the two phones are not exactly the same? Mine is the Xperia Miro, just wondering.
